Specification of Letters Patent.

Patented Feb.. 4, 1219.

Application led May 18, 1918. Serial No. 235,297.

To all 'whom t may concern Be it known that I, WJILIAM F. MnssrrER, a citizen of the United States, residin at Brooklyn, in the county of Kings and State of New York, have invented a new and useful Heater, of which the oliowing is a specilication.

The device forming the subject matter of this application is adapted to be employed for raising the temperature of water, and the invention aims to provide an improved heater through which the water passes, novel means being provided for securing a proper circulation of the products of combustion about the heater.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the present invention appertains.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, witho ut departing` from the spirit of the invention.

In the accompanying drawings Figure 1 shows in vertical longitudinal section, a device constructed in accordance with the invention, parts appearing in elevation;

Fig. 2 is a longitudinal section taken in a plane different from the cutting plane in Fig. 1, the central portion of the device beino broken away and parts being omitted;

Fig. 3 is a cross section on the line 3-3 of Fig. 1; y

Fig. 4 is a cross section on the line 4-4 of Fig. 1; and

Fig. 5 is a cross section on the line 5*-5 of Fig. 1.

The device forming the subject matter of this application includes a hollow base 1 within which is disposed a burner 2 or any other suitable heating means. The invention embodies an upright tubular casing, denoted generally by the numeral 3 and including an inner wall 4, an outer wall 5 and a packing 6 between the walls, the walls of the casing being supported on the base 1. The casing 3, is surmounted by a closure 7, including a top plate 8 mounted on the upper end of the inner wall 4 and extended laterally into contact with the outer wall 5, the closure embodying a cap 9 supported on the outer wall 5, and a packing 10 interposed between the cap and the top plate 8.

` Located within the casing 3 is an upright tubular tank 11 closed at its upper and lower ends and including an inner wall 12 and an outer wall 14. An annular lower ange 15 extends laterally from the outer wall 14 of the tank to the inner wall 5 of the casing 3 and is supported on the upper end of the base 1. An upper flange 16 extends laterally from the outer wall 14 of the tank 11 and contacts with the inner 'wall 5 of the casing 3. As 'shown in Fig. 3, the flange 16 extends but part way around the tank 11, to form an opening 17 communicating with the chamber 18 which exists in the upper end of the casing 3 above the tank 11. The tank 11 may carry any desired number of spacing lugs 19 coperating with the inner wall 4 of the casing 3. Oppositely disposed vertical batlies 22 extend downwardly from the ends of the upper flange 16 and terminate, as shown at 23, in spaced relation to the lower flange 15. The baffles 22 form, between the tank 11 and the casing 3, oppositely disposed flues 20 and 21, each of which is of semi-circular cross section. The flue 20 is closed at its upper end by the Hange 16 and is closed at its lower end by the flange 15. rlhe lower end of the iue 21 is closed by the ange 15, but the upper end of said flue communicates with the chamber 18 through the opening 17. A stack 24 passes upwardly through the closure 7 and Opens at its lower end into the flue 20, through the upper flange 16.

Disposed within the central opening of the tank 11 and spaced from the inner wall 12 of the tank tp form an annular flue 50, is a water heater which is a composite structure.

The heater embodies a series of units each comprising a tubular hub 25, an outertubular ring 26, radial connectlons 27 between the hub and the ring, and connections 28 projecting upwardly and downwardly from each ring, theconnections 28 on one ring coacting with the corresponding connections on the next adjoining ring to form vertical water passages, the hubs 25 ofthe units abutting to form a central water passage. Extended vertically through the central water passage delined by the hubs 25 is 30 which extends inwardly into contact *with the pipe 29, so as to close the upper endof the space existing between the outer wallof the pipe and ,the innerwalls of the hubs 25.Y

The lower unit of the heater has a similar flange 30 which closes the bottomnof the;

space above alluded to. A collar 31 is threaded on the upper end ofthe pipe 29 and engages the upper flange 30, therebeing superposedfnuts y32 oir the lower .endfot the pipe which coact with ther-lower flange '30, thepipe 29,the collars Bland nutsfBQ-Jconstituting a part of the means forfholding the units of the heater together.:` Superposed-on the luppermost unit of i the kheater is 4a `.top drum. 33 including a ring 34, a. hub 135', radial connections BH1-between'` the ringl andi the hub; and depending tubular "connections 137 which set against and communicatewvithithe upright -connectionsQS of the .uppermost 'unit of thelieaterr Theheater:includesfa unit disposed adjacent the bottom oftheeheater and comprising a.- ring 38,'fan :uprightconnectiony 39, i the unit in: question `being idevoidi of a central hub like thevpart.I` Theiupper endsl ofthe connections 39fco1nmunicate with the connectionsf28 of lth'e'nextsuper-posed .member of the heater, the :lower ends l,of-` the connections 39 communicating -gwithr a ybottom drum 40: Theu bottomi drum Opthe `top drum ,33 and 'parts therebetween@ arefsupplied with vertical ribs 41,; locatedfion the upright tubular connection, as shown .finfFig 2.' Securing devices, such'asdrawf bolts 112, pass-through the ribs #il andhold the-'units of the .heater together-. In practical-` loperation,the units ofthe heaterare madesepa- .ratel.y, their 4meeting 1 edges- :may 'be brazed together, and :thefdrawtv bolts42 fholdffthe units togethei',rand prevent their separation.

Avmain outlet pipe 'tlpasses through @the closure l7 and communicates V'withf the .-hub B5 of thetop drum 33:* The partelisfsupplied withl lateral dep ending branches opening into; the tank, 11 at diametricavlly opposite points, and at thetop of thefta'nln Bymeans of connectionse `shown inaFig. 2,':the :lower end of A"thertanlr-.wll communicates with the drum 40: I The druni LOfissuppliedqwit-h oppositely disposed inletA pipes Ll6-,fone ,ot which may be closed if desired.

Inapractical operation; the :products of combustion ronrfthe bur-ner @pass-upwardly through thefflueybetween .fthetankvll and .the heater, and enter :thechamber- "18N Similarly, the` products of.` combustione fromi 'the burner Y2 pass upwardly f through the; 'bottom drum 4:0, 1 and- :the next supenposed-f .untw'of the heater, vtheproducts oxconrbustion :traversing thefcombustionwpipe.e29rso-asz to; 1hea-t the water rinthe ihubsfQi Thexfprod-ucts of combustion: =pass:1upwardly#around@ the radialiI Iconnection'svg andesincaethe: connections are disposed out of alinement, as shown in Fig. Ll, the water in the connectionsw-ill'flbe heated. The products are first delivered into the chamber 18 but cannot pass directly out of the stack 24;, because the stack communicates with the flue 20, but not with the chamber. Consequently, the-productsLol combustion pass downwardly through the opening 17, along the flue 2l, through the openings23-at the lower ends of 'the lniitles "22, upwardly throughl the flue 20 and out of the stackQe.

The, water delivered into the drum Zl() through one of. the pipes i6 traverses the rings 26,the hubs 25 and the radial connections 27, and is heated to a high degree. l/Vhein the heated waterl is delivered into the topfdrum 33, water passesinto theinain outletpipe @L3 and thence to :ther place of use. If sufficient 4quantity of water is` not permitted 4to'flowthrough the piperl, then the water .1' will Itravel downwardly through the branches ad, intofthe't-aiikll, and out of' `the tank through the connectionsfuinto the lower drum 40, kan-equalizing.circuit thus beingfinaintained.-
